However, even if the finished size is the maximum, no skin is left.

As shown in FIG. 5B, the positional relationship between the thickness of the insulating sheath 1 and the blade 3 is determined by the thickness d2 of the insulating sheath 1 of the cable 2 and the depth d3 of the blade 3 cut into the cable 2. Is usually an approximate value, and even if the thickness d2 of the insulating sheath 1 of the cable 2 is the minimum of the finished dimension, a thin skin of about 0.1 mm remains. The depth d5 of the wedge 5 biting into the cable 2 and the depth d3 of the blade 3 cut into the cable 2 are based on the thickness of the insulating sheath 1 of the cable 2 and the wedge 5 and the blade 3 are respectively located at predetermined positions.

A cut is formed by operating the circular blade 13 so as to move in the length direction of the cable 2 as shown in FIG. 6A.

As shown in FIG. 6B, the positional relationship between the thickness of the insulating sheath 1 and the wedge 5 is determined by the thickness d2 of the insulating sheath 1 of the cable 2 and the depth d of the wedge 5 biting into the cable 2.
5 is set to the same value as usual, so that no thin skin remains even if the thickness d2 of the insulating sheath 1 of the cable 2 is the maximum finished dimension.

As shown in FIG. 6B, the positional relationship between the thickness of the insulating sheath 1 and the circular blade 13 is determined by the thickness d 2 of the insulating sheath 1 of the cable 2 and the depth of the circular blade 13 cut into the cable 2. The thickness d13 is usually an approximate value. Even if the thickness d2 of the insulating sheath 1 of the cable 2 is the minimum of the finished dimension, the value is 0.1 mm.
The skin of about 1 mm is left. The depth d5 of the wedge 5 that cuts into the cable 2 and the depth d13 of the circular blade 13 that cuts into the cable 2 are determined at predetermined positions based on the thickness of the insulating sheath 1 of the cable 2. Adjust the position and fix.

Further, if the roller 10 is formed in a form in which a V-groove is formed, even if the direction switching mechanism is omitted, a cut can also be formed in the circumferential direction of the insulating sheath so that a round cut can be performed.

With this, the cutting tool forms a cut in the circumferential direction of the insulating sheath and constitutes the direction switching mechanism so that the cutting can be performed. Therefore, a cut can also be formed in the circumferential direction of the insulating sheath, and the cutting can be performed. Longitudinal tearing and rounding can be performed.

In this way, the cutting tool that forms a cut that allows the insulating sheath to be longitudinally split and the wedge that expands the formed cut are used to insulate the cable so that the inner core of the cable having the insulating sheath can be taken out. The provision of the position adjusting mechanism capable of adjusting the variation of the finished dimension of the sheath thickness enables the blade and the wedge to longitudinally tear the cable provided with the insulating sheath so that the inner core of the cable can be taken out without damage.

FIG. 9 is a view showing another embodiment of the present invention, and shows a detailed view of a main portion when a V-groove is formed in the roller 10. As shown in FIG.

In order to visually confirm the depth d13 at which the wedge 5 is cut and the depth d5 at which the wedge 5 cuts into the insulating sheath 1, the circular blade 1 is used.
For example, a concentric mark is formed by a thin line formed by printing, laser processing, or etching every 0 or 2 mm from the outer circumference of 3.

In addition to the actual position scale, the use of the above-described position adjusting mechanism allows the inner core to be split vertically without further damage.

With this configuration, since the blade has a position scale so that the depth of the cut formed in the insulating sheath can be checked, the depth of the cut formed in the insulating sheath can be checked, and the inner core of the cable can be checked. Can be taken out without damage.

Next, the blade constitutes a position adjusting mechanism for adjusting the positions of the insulating sheath and the cutting edge of the blade so that the depth of the cut can be controlled.

[0094] With this configuration, the blade has a position adjusting mechanism so that the depth of the cut formed in the insulating sheath can be controlled. In addition to the above-described effects, the depth of the cut formed in the insulating sheath can be controlled. The cable can be taken out without damaging the inner core of the cable.

Further, the blade has a position scale indicating the cutting depth of the cutting edge of the blade into the insulating sheath so that the depth of the cut can be confirmed.

In this way, since the blade has a position scale so that the depth of the cut formed in the insulating sheath can be checked, the depth of the cut formed in the insulating sheath can be checked in addition to the above-mentioned effects. Thus, the cable can be more reliably taken out without damaging the inner core of the cable.
